The cost of a television is $429.99 after sales tax is added. If the sales tax is 7.5%, what was the cost of the television before sales tax was added? (A) $377.74 (B) $389.46 (C) $397.74 (D) $399.99 (E) $459.27

Answers

Answer 1

The total cost before sales tax is $399.99

Answer 2

The original cost of the television before a 7.5% sales tax was added, which made the total $429.99, is optionD. $399.99.

The question is asking to find the original cost of a television before sales tax was added. Given that the final cost after including the 7.5% sales tax is $429.99, we need to find the price before this tax was applied. To calculate this, we first convert the percentage to a decimal, which is 0.075, and then create an equation to represent the relationship between the original price (let's call it x) and the total cost with tax. The equation would be x + 0.075x = $429.99. This is equivalent to 1.075x = $429.99. Solving for x gives us the original price of the TV before tax.

To solve for x, we would divide both sides by 1.075, which is the combined total of the original price and the tax. x = $429.99 / 1.075. This calculation gives us the original price of the TV, which turns out to be $399.99, which is option (D).

What is the y intercept of y = 6x + 32?

Question 4 options:

6

6x

32

0

Answers

To find out the y-intercept of a function, we fill in x = 0

This gives us the following:
y = 6 * 0 + 32 = 0 + 32 = 32

So, the y-intercept is 32.

Final answer:

The y-intercept of y = 6x + 32 is 32.

Explanation:

The y-intercept of a linear equation is the point where the graph of the equation intersects the y-axis. In the equation y = 6x + 32, the y-intercept is the value of y when x is equal to 0. To find it, substitute 0 for x in the equation: y = 6(0) + 32. Simplify the equation to find that the y-intercept is 32.

A rectangular prism has a length of 112 meters, a width of 3 meters, and a height of 512 meters.

Enter the volume of the prism as a mixed number in simplest form in the box.

Answers

Answer:

[tex]Volume=24\frac{3}{4}m^3[/tex]

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula;

[tex]Volume=l \times w\times h[/tex]

where [tex]l=1\frac{1}{2}m[/tex] is the length, [tex]w=3m[/tex], is the width and [tex]h=5\frac{1}{2} m[/tex] is the height of the rectangular prism.

We substitute all these values into the formula to obtain

[tex]Volume=1\frac{1}{2} \times 3\times 5\frac{1}{2}[/tex]

Convert to improper fractions to get;

[tex]Volume=\frac{3}{2}\times 3\times \frac{11}{2}[/tex]

Kit bought a soft drink and a sandwich for $9.00. What was the price of each if the sandwich cost 3.5 times much as the soft drink?

Answers

Let the cost of the soft drink = C then the price of the sandwich was 3.5 times as much = 3.5C

And

C + 3.5C = Total Cost

C + 3.5C = 9

4.5C = 9 divide both sides by 4.5

C = 9/4.5 = $2.00 for the soft drink

And 3.5C = 3.5(2.00) = $7.00 cost of the sandwich

If Kit bought a soft drink and a sandwich for $9.00 and the sandwich cost 3.5 times much as the soft drink the price of the sandwich and soft drinks will be $7.00 and $2.00 respectively.

What are arithmetic operations?

The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.

It is given that, Kit spent $9.00 on a soft drink and a sandwich, with the food being 3.5 times as expensive as the soft drink.

Suppose the cost of the soft drink is x as a result the price of the sandwich will be 3.5x.

Total cost = $9

x+3.5x=9

4.5x=9

x=9/4.5

x= $2.00

The price of the sandwich obtained as,

=3.5x

=3.5× $2.00

=$7

Thus, if Kit bought a soft drink and a sandwich for $9.00 and the sandwich cost 3.5 times much as the soft drink the price of the sandwich and soft drinks will be $7.00 and $2.00 respectively.

what is between 3/8 in a number line

Answers

Okay I hope this is what you mean. so if you are saying what is between the numbers 3 and 8 we can make an inequality which will cover all the small decimals between the numbers.

There are 2 different equalities that I'm not sure which one you want.

so the first one would be
[tex]3 \leqslant x \leqslant 8[/tex]
x is just the variable I chose for this. Now this inequality means that both 3 and 8 are solutions to the problem. x represent all the little numbers in between so to test your answers just plugin the number you're testing in for x. Since 3 is the lowest number it will have a less than or equal to (in this case) sign and 8 is the greatest so that's why the open/greater side is facing the 8. It reads 3 is less than or equal to x and x is less than or equal to 8.

If you meant all number in between 3 and 8 not include either of those numbers than the inequality would be
[tex]3 < x < 8[/tex]
In this case all the numbers between 3 and 8 are solutions but 3 and 8 will not be solutions. the line under the symbol means it includes the number which come before or after it. The inequality reads 3 is less than x which is less than 8. You can also plugin in an answer to test it in place of x.

If you have any questions or it turns out you meant somthing else please tell me and I'll be happy to help, sorry if this isn't what you meant in the question.

Answers

can you please rewrite the question there are a few typos.

Jessie set up a lemonade stand for three days.

On Saturday she sold 10 and 2/3 gallons of lemonade = 10+2/3 = 32/3 gallons

On Sunday she sold 3 and 1/3 gallons more than she sold on Saturday

Lemonade sold on Sunday = 32/3 + 3 and 1/3 gallons

= 32/3 + 10/3 = 42/3 gallons = 14 gallons

On Monday she sold 2 and 2/3 gallons less than she sold on Sunday

Lemonade sold on Monday = 14 - 2 and 2/3 gallons

= 42/3 - 8/3 = 34/3 gallons

Therefore, Jessica sold 11 and 1/3 gallons of lemonade on Monday

Here, h= b-9
A=56 m^2
Put values in formula.

56=b(b-9)/2
Multiply both sides by 2.
112=b^2-9b
or
b^2-9b-112=0
Factorise the equation.
b^2-16b+7b-112=0
b(b-16)+7(b-16)=0
(b+7)(b-16)=0
Using zero factor theorem.
b+7=0 or b=-7

b-16=0 or b=16
Ignore the value b=-7, because length cannot be negative.

The half-life of a radioactive substance is the average amount of time it takes for half of its atoms to disintegrate. Suppose you started with 200 grams of a substance with a half-life of 3 minutes. How many minutes have passed if 25 grams now remain? Explain your reasoning.

Answers

3 half-lives because 200/2=100 100/2=50 and 50/2=25

Answer:

It would take 9 minutes for 25 grams of the substance to remain.

Step-by-step explanation:

Radioactive substance degenerate to release particles and lot of energy. The time required for a radioactive substance to degenerate into half of its original size is termed half life. The substance continues the stages of degeneration with respect to the half life.

The given substance would have 3 stages of degeneration to achieve a mass of 25 grams with respect to the half life.

1st stage, it would degenerate to half of its original size;

= [tex]\frac{200}{2}[/tex]

= 100 grams

This occurs in 3 minutes.

2nd stage, it would degenerate to half of its previous size;

= [tex]\frac{100}{2}[/tex]

= 50 grams

This also occurs in 3 minutes.

3rd stage, it would degenerate to half of it previous size;

= [tex]\frac{50}{2}[/tex]

= 25 grams

This also occurs in 3 minutes.

We stop here due to the restriction in the question for 25 grams.

So, the total time taken for the substance to reach a mass of 25 grams

= 3 + 3 + 3

= 9 minutes

It would take 9 minutes for 25 grams of the substance to remain.

Hank bought 3 guppies and 4 platies for a total of $18.33,

Write the equation of the above statements as shown below,

3g + 4p = 18.33

Here, g is the price of guppies and p is the price of platies,

Solve the above equation by elimination as shown below,

3g + 2p - (3g + 4p) = 13.95 - 18.33 (Subtract equation from each other)

3g + 2p - 3g - 4p = -4.38

p = 4.38 / 2

p = $2.19 and,
